Why pultruded grating?
Advantages
Light weight, high strength— easier to transport and install with standard toolsCorrosion resistant— won’t rot or rust and absorbs minimal moistureChemical resistant-mild acid-alkali proofHumidity resistant— no shrinking or swellingImpact resistant — fiberglass mat distributes the load to prevent surface damageSafety — won’t conduct electricity, and non-slip surfaces are availableLong-lasting— lower lifetime cost than traditional building materialsLow thermal conductivity — does not easily conduct heat or coldNon-electrical conductivity, with non magnetic propertyMechanical Properties of Pultruded Profiles Vs.
